"Rubral" tremor due to midbrain Toxoplasma abscess
1Department of Neurology, New York Medical College, New York.
Summary
A midbrain abscess caused by Toxoplasma gondii led to a persistent rubral tremor in a patient. Even with effective treatment that partially resolved the lesion on CT scans, the tremor did not improve.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Toxoplasma gondii infections can cause central nervous system (CNS) lesions.
- Rubral tremor is a type of involuntary movement disorder characterized by a combination of resting, postural, and intention tremor.
Observation:
- A patient presented with a rubral tremor attributed to a midbrain abscess caused by Toxoplasma gondii.
- Computed tomography (CT) imaging was used to visualize the abscess.
Findings:
- Treatment led to partial resolution of the Toxoplasma abscess in the midbrain, as evidenced by CT scans.
- Despite the partial resolution of the abscess, the patient's rubral tremor persisted without improvement.
Implications:
- This case highlights the potential for persistent neurological deficits, such as rubral tremor, following CNS toxoplasmosis.
- It suggests that the resolution of the causative lesion may not always correlate with the improvement of specific movement disorders.
- Further research may be needed to understand the mechanisms underlying persistent tremors in CNS infections and to explore targeted therapeutic strategies.
